WebMar 21, 2024 · Quicksort is a sorting algorithm. The algorithm picks a pivot element and rearranges the array elements so that all elements smaller than the picked pivot element move to the left side of the pivot, and all greater elements move to the right side. Finally, the algorithm recursively sorts the subarrays on the left and right of the pivot element. WebThe quicksort algorithm is essentially the following: Select a pivot data point. Move all data points less than (below) the pivot to a position below the pivot - move those greater than or equal to (above) the pivot to a position above it. Apply the algorithm to the areas above and below the pivot. netherlord\u0027s accursed
